查询词典 activation process

The pathogenesis of asthma can be divided into three stages in immunology. The initial stage is sensibilization, which is closely associated with the activation of T cells. B7/CD28 and CD69 also play a significant role in this process. The second stage is chronic allergic inflammation. The immune dysfunction resulting from the disturbance of TH1/TH2 is a major cause of chronic allergic inflammation, and dominates asthma attack. And the third stage is airway remodeling due to chronic inflammation. Airway remodeling is one of the major causes of refractory asthma, which also contributes to the death from asthma.

哮喘的发病从免疫学角度可以分为三期：初期为致敏阶段，与T细胞激活关系密切，B7/CD28和CD69在这一过程也扮演重要角色；第二期为慢性过敏性炎症阶段，TH1/TH2失衡导致免疫功能紊乱是此阶段的主要原因，在哮喘发作过程中起主要作用；第三期为慢性炎症引起的气道结构重构阶段，是难治性支气管哮喘的重要发病和死亡原因。

The effects of many parameters, such as the amount of surfactant, airflow rates, pH, NaCl, ethanol and temperature on the solvent sublation were studied. Experimental results showed that a ratio of surfactant to Pb-dithizone complex (2∶1) was the most effective for the removal, with over 97.4% Pb removed from the aqueous solution in 40 min by solvent sublation, at the value of pH 12.6.The solvent sublation process followed first order kinetics. A characteristic parameter, apparent activation energy of attachment of the sublate to bubbles, was estimated at a value of 2.08 kJ/mol.

结果表明，当表面活性剂与硝酸铅物质的量之比为2∶1时，铅去除率达97.4％；体系去除率在pH值为12.6时最高；有机溶剂的影响不明显；少量的乙醇可提高其去除率和去除速率，但过多会产生抑制作用；适量的NaCl能提高体系去除率，但随着浓度的提高呈现下降趋势；去除速率随气流速率增加而增加，体系去除率随温度升高而递增；反应过程遵从一级动力学，表观活化能为2.08 kJ/mol。

In order to explain the phenomenon, the process of activation sulfurization of LaCoO 3 in the presence of oxygen was studied by XPS, XRD and TEM methods.

在氧化气氛下预处理会产生更多的阳离子空位，从而使其CO高温氧化活性明显升高；在还原气氛下预处理会产生更多的氧离子缺陷，从而使其CO低温氧化活性明显升高[1] 。
